Aftermarket Muffler Repair
A few years ago these came to me due to some internal rattle on a 996. Instead of spending money fixing old mufflers (I think they are GHL’s), the customer upgraded to new Fabspeeds. Instead of tossing them, I hung on to them for some reason. I came in on Sunday to see if I could do anything with them. I cut the cans open and found a bunch of broken screens, etc that had been rattling. So I gutted them and closed them back up. Should be a good exhaust note:
After welding everything back together.
And a little high temp paint. Can’t wait to install them.

The mufflers on my 996 are making that same rattle! Temporarily I just took the mufflers off and bought some 2-1/8″ mandrel bent 90s and am running those out the back. I think I’ll cut the muffler apart and try removing the screens like you did here. Have you tried these out after removing them? How does it sound? (My home-built bypass pipes are waaaay too loud)

Hi Mark,
If you are still running the stock mufflers, you can open them up and reweld the broken baffles to repair them. These were a little different as they are aftermarket, they were aggressive when back on the car, but not like muffler bypass pipes 🙂
The broken internal baffles on the OEM mufflers is a fairly common issue.
